How is her mobility? Is she walking tall or does she drag her back legs occasionally? Getting exercise is another important part of tortoise rehab - I would be working on a much larger enclosure for her if you are not already doing so. Russians are a very active tortoise and need a lot of space to move around. Some people build multiple story tortoise enclosures if they don't have a lot of floor space to offer. If she is mobile, she will appreciate having more room. It will also help you keep her food and water dishes clean - when they are in tiny enclosures they seem to get substrate everywhere, but when there is enough room they don't have to continually walk through their dishes.
